WEHAM-Subproject 2: Development of WEHAM scenarios

Background and Objective

In this sub-project, different scenarios of forest management (based on stakeholder interviews) will be compiled and used in simulations with WEHAM. The results of the simulations will be analysed with regard to sustainability, climate protection and biodiversity indicators.

Approach

WEHAM projects the growth of individual trees into the future. The growth equations used are derived from repeated measurements in the National Forest Inventory (NFI). Each tree tallied in the NFI can be included in the simulations. A single tree represents a certain number of trees of the same genus, age and size. According to a given management scenario. the trees are "treated", i.e. some of the represented trees are "cut" and their timber handed over to e. g. a wood products model. The "remaining" trees grow on, til the next modelling step. Depending on the intended analysis, the results can be aggregated from tree to various regional levels (e.g., federal state) and / or other classifications (e. g., age classes).

Results

• Different scenarios based on results of stakeholder dialogues
• publication of scenarios and their results on forest management options with the respective ecological limits of ecosystem dynamics and forest growth
• regional information of scenarios, particularly on forest growth, carbon sequestration and potential timber use
